wIzeE-rarrnaj To all whom it mag) concern: i

Be it known that I, STANLEY J. PUKROPP, a lcitizen of the United States, residing at Sturgeon Lakeyinthe county of Pine and State of Minnesota, have invented certain new and useful Improvements in Wire-Tappers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled inthe art to which it appertains to make and use the same.

My invention has flor its object to provide an improved wire ta per and, to this end, it consists ofthe nove devices and combinations of devices hereinafter described anddened in the claims.. y 4 In the- Vaccompanying drawings, which illustrate the invention, like characters indi- Referring to the drawings: Figure 1 is a View in side elevation showing a telephonev mounted in an automobile' and connected with the line wires; Fig. 2 isa view 1n side tions; Fig. 3 is adetail lview of the contact grapples, on an enlar ed scale, with some parts sectioned on the ine ao* of Fig. 2;..

an automobile and the numeral 2 Aindicatesa telephone pole having secured to its upper end the customary cross arms 3 `which `are provided with insulating caps 4, to. each of which is secured a line wire 5. To the inner/.vertical facejof the dash board of they automobile 1 is attacheda box containing The numeral 8 indicates a, receiving and transmitting instrument, and the numeral 9 indicates the two wires of the instrument battery circuit. The'wir'es of this instrument circuit are attached one to eac-h of a pair of upwardlyl divergmg'contact grapples 10 having, on their outer edges, a. plurality of longitudinally spaced hooks 11, for

engagement with the linel wires 5. "At their lower ends, the contact grap les 10 are pivotally secured, for independent movement toward and from each other, on a pin 12 e wiring` specification of ruiters Patent. i Patented June 16, 19144. appuaion'mea august so, i913. serialn'o. 787,445. l

anchored, at its'end's, inl a socket 13 lsecured tothe upper end of a long rod 1'4'adording a handle for said grapples. The contact -grapples 10 are insulated one from the other and from the pin12-by a bushing 15 of suit- Y ablel insulating material. The rod 14v is madel up of. a plurality of sections detachably connected by couplings 16 of substantially thesalne .construction as an ordinary hose coupling.v The couplings 16 comprise internally threaded sleeves 17 telescoped onto lthe lower ends of the rod sections with freedom for rotation thereon but held upper endsof the sections of the rod 14.

Disks 2O of insulating .material close lthe ends of the rod sections. 1

The instrument `circuit wires 9 are longi- 7 tudinally. extended'through the rod 14 Iand y are severed and detachably. connected, at elevation of the improved telephone connecy each joint thereof, by separable contacts 21 and 22. The contacts 21 are in the form olf'l depending fingers secured to the disks 20 in the lower ends of the rod sections and ar- A yranged-'t0 enter sockets 23 formed in the disk 20 of the u`pper ends of the rod sections, for

engagement with the contacts '22, which are the formof fiat s rings. Obviously, the contact fingers 21 ce the rod sections properly alined and 'he d against rotation with respect .to each other.

other by the contact fingers 21 and sockets 28.` The instrument and light circuit wires are all properly insulated and, from thebatteiybox 6 to the lower end of the roii 14, they are in the form -of a single cable. In the light battery circuit 26 is a normally open. switch 28 mounted -on the lower end portion ofthe rod 14.

By meansof the handle or rod 14, the conectriclamp 24 is mounted on a lamp4 ica xtactigrapples 10 may be applied to any one pair of the line wires 5. The hook equipped- I upwardly diverging grapples 10 permit 'the device to be attached to line wiresset various distances apart and also tov Wires-that extend in the, same horizontal plane or wires llocated one above ,the other. The depending handle or rod 14 holds the grapples l0.

in proper contact with the line Wires 5. When the device is not in use, the contact several sections of the rod 14 may be .separated and placed within the automobile in a compact space. In the operation ofthe de- ,l vice, two or more rod sections 'may be used,

, lamp 24: may be lighted, to illuminate the grapples 10 so that the operator may readily apply the .same to the line Wires.

From the foregoing descriptiorn'it is evident that, by the use pi." the improved device, telephone connections may :be made anywhere along the line Wires. In case the connections are not long' enough-to reach from the automobile to the line wires, the entire device may be removed from the automobile and carried tothe line wires.

What I claim is'.

l. A line tapper comprising a rod having va contact grapple for engagement with a Aline circuit, wire connections leading to said grapple, and a lamp supported onsaid pole in the vicinity of saidL grapple,

2f. A wire tapper comprising'a battery, a receiving and transmitting instrument, a rod' having contact grapples, for engagement with the line wires, instrument wires connecting said grapples with said battery, an electric lamp' supported by said rod in the vicinity of said grapples, and lamp circuit wires connecting said lamp to said battery.

.f A wire tapper comprising a battery, 'a

-receiving and transmitting instrument, a rod made up of jointed sections',icontact grapples at one end of said rod, for engagementy with the line wires', and instrument wires extending through said rodand con meting-said grapples with said battery, said instrument 4wires having separable contacts at the-joints of Said rod.

4. A Wire tapper comprising a battery, a receiving and transmitting instrument, a rod' made up of jointed sections, contact; grapplesr at one end of said rod Vfor engagement with the line wires, instrument wires extending through said rod and connecting said grapples with said battery, an electric lamp Supported by said. rod in the vicinity of said grapples, and lamp circuit wires extending through said rod and connecting' said lamp with said battery, said instrument and lamp circuit wires having separable contacts at l the joints of said rod. grapples 10 may be folded together and the 5. A wire tapper comprising a battery, a receiving and transmitting instrument, a rod having, at one end, foldingcontact grapples for engagement with the line wires, and instrument wires connecting said grapples with said battery.

Awire tapper'comprising a. battery, a receiving and transmitting instrument, a rod, a pair of diverging contact grapplee attached to one end of said rod and having longitudinally spaced hooks for engagement with 'the line wires, and instrument `Wires connecting said grapples with said battery. 7. A wire tapper comprising a battery, a receiving and transmittinginstrument, a rod made lup of jointed sections, a pair of folding diverging Contact grapples attached to one end `of said rod and having longitudlnally spaced hooks for engagement with the line wires, and instrument wires extending through said rod and connecting said grapples with said battery, said instrument wires "having separable contacts at the joints of said rod.

8. A wire'tapper comprising a battery, a receiving and transmitting instrument, a rod made up of jointed sections, a pair of folding diverging Contact grapples attached to one end 0f said rod andV having longitudinally spaced hooks for engagement with the vline -wires, instrument, wires extending through said rod and connecting saidgrapples with 'said battery, an electric lamp supported by said rod in the vicinity of said 'g1-apples, lamp circuit wires extending,"
